STRIKING-BAG SUPPORT;

Specification of Letters Patent.-

Iatented July 1,1913.

Application filed October 7, 1912. Serial No. 724,260.

To all whom it may concern:

Be it known that 1, PETER RANK, a citi- Zen of the United States,residing at St. Paul, in the county of Ramsey and State of Minnesota,have invented a new and useful Improvement in Stril'iing-Bag Supports,of which the following is a specification.

This invention relates to an improved striking bag support and has forits pri mary object, simple and inexpensive construction which can beeasily made from ordinary stock material and which is strong and durablein use.

in the accompanying drawing forming part of this specitication, Figure 1is a perspective oil my invention; Fig. 2 is a section through one ofthe supporting arms and the ring showing the method of securing saidparts together; Fig. 3 is a perspective ot a spring washer which is usedbetween the bolt and supporting arms illustrated in Fig. 2 and Fig. 4 isa detail, part of which is shown in section.

In the drawing 2 represents a ring which is supported in a horizontalplane and against which the striking bag 3 is adapted to impinge when inaction. The ring 2 is supported by horizontal bracket arms t and 5 andan upwardly slanting arm 6. Near the center oi the ring is a union 7with which the arms 4:, 5 and 6 are connected by threading, said arms 4and 5 being arranged at right angles to each other and secured to thering by bolts 8. The arms 4: and 5 are bent obliquely at 9 to extendbackwardly to the wall or other supporting object to which their endsare secured by bifurcations 10. In alincment with the portions (it thearms i and 5 which are arranged at right angles, are two oppositelyarranged arms 11 and 12 which are secured into the union 7 by threadsand their outer ends fastened to the ring by bolts 18. A spring washerl-t (see Fig. 3) is placed between the heads of the bolts 8 and 13 andthe arms which they secure to the ring for the purpose of holding thebolts tight. The arm 6 is fastened into the upper central portion of theunion 7 by threads and is bent back to the support to which the arms atand 5 are adapted to be secured. The arms 4, 5 and G are adapted tosupport the ring rigidly from overhead, allowing the striking ball freeplay below.

Into the lower central portion of the union 7 a depending arm 15 issecured by threads and to the lowcrextremity of said dependlng arm acentrally apertnred cup 10 1s secured which is threaded to the arm 15and adapted to hold a bushing 1.7 made of relatively soft material suchas wood. The striking ball 2-; is hung from the lower extremity of arm15 by its cord 18, the upper endoi which is knotted at 18) above thebushing 17 in the cup 16, said bushing having a centrally disposedpassage 20 in which the cord is free to play or swivel. The bushing hasa nipple 21 projecting downwardly through the cup, the inner surface ofsaid nipple being curve-d at 22 to prevent abrading of the rope 18 bythe swinging action of the ball.

The supporting parts described composed of the ring, and arms areadapted to be made out of ordinary stock pipe or tubing which is aconvenience and an advantage in constructing the apparatus.

In use the arms 4, 5 and 6 are adaptcd'to be secured to a support suchas a wall by inserting screws through the bifurcations 10 and the flange23, the ring 2 being adjusted in a horizontal plane. The striking ballis then secured by its cord in the swivel end of the arm 15, the cordbeing adjusted in length so that the ball will swing against the ringwhen in action.

In ttti(.()1'(l:lllti0 with the patent statutes I have described theprinciples of operation of my invention together with the apparatuswhich I now consider to represent the best embodiment thereof but 1desire to have it understood that the cmistruction shown is onlyillustrative and that the in vention can be carried out by other meansand applied to uses other than those above set forth within the scopeoi. the Following claim.

Ilaving described my invention, what I claim as new and desire toprotect by Lettors Patent is A striking ball support, comprising, incombination, a horizontal ring, a union concentric to said ring, armsradiating from, and threaded to said union and secured to the upperportion of said ring, part of said arms projecting from said ring and.t'orming brackets adapted to be secured to a supporting object, anoverhead arm threaded down into said union and extending back and abovesaid ring and adapted to be secured to a supporting object, a downwardlyextending arm on said union, a cup secured over the lower extremity ofsaid In testimony whereof, I have signed my downwardly extending arm, apassaged name to this specification, in the presence L0 bushing securedby said cup to the lower of two subscribing witnesses.
